10 The Conservation of Ecological Interactions
... It is relatively straightforward, if time-consuming, to determine the parasitoids of a given host species. The host insect is reared in isolation until either an adult host or a parasitioid emerges (Memmott and Godfray, 1994; Memmott, 1999). However, in spite of the relative lack of obstacles (in co ...

Conservation biology
Conservation biology is the scientific study of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management.The conservation ethic is based on the findings of conservation biology.
